Don Ghiz Invites Members to Attend the May Meeting and Watch for Pests
Hello everyone,
Welcome to May 2025. This month’s meeting will hopefully enlighten us all about how the Houston Orchid Society is to grow in an uncertain environment of personal pressures from work, school, home, and so many duties that take us away from our hobby. That said, I would make an argument that those pressures make being active in the hobby even more important. I’m optimistic that we will find a way to grow in a very time-competitive environment. The meeting is only a few days away (Thursday, May 1).
Let’s turn our attention to our orchids. It’s May, and they deserve attention after their springtime growth. I’m reminded that insects such as slugs, snails, scale, mealy bugs—well, the list goes on—are recovering from winter and are hungry. Please take a moment to look closely at your collection. Examine the undersides of leaves where these culprits hide from us. It’s beyond the scope of this message to detail treatments, but the Internet and, indeed, the AOS website can be a big help. My only caution is to follow label directions closely and always repeat applications in a week or two because many insect larvae are not affected by the treatment that kills adults. So it’s important to hit them again after they have hatched and before reaching reproductive age.
May may also be a good month to repot your plants. If they’ve grown too tight for the pots or the potting mix has broken down, give them a fresh start in a slightly larger pot and fresh mix. They’ll thank you by surviving the hot summer months ahead.
My final thought this month is about Houston water and fertilizer. We’ve all heard the expression that goes “Water weakly weekly.” Indeed, orchids don’t need a lot of fertilizer. As epiphytes, they thrive on nutrients that come in rainfall. The trouble is, rainfall is more acidic than Houston water, so you might explore adding an acidifying agent to your water. Your plants need water in the pH range of 6.8 to absorb the nutrients. So again, I suggest finding ways to acidify your water. Your plants will thank you for this, too.
Happy growing and all my best,
Don Ghiz
